Abstract
The invention discloses a frame type rail bearing beam structure which comprises a reinforced concrete bottom board located between two bottom board backfill top face lines. Two reinforced concrete girders are arranged on the upper surface of the reinforced concrete bottom board and fixed to the reinforced concrete bottom board. Reinforcing ribs are vertically arranged in the reinforced concrete girders. The bottoms of the reinforcing ribs penetrate the reinforced concrete girders to be fixed to the reinforced concrete bottom board. The tops of the reinforcing ribs are fixed to the inner top faces of the reinforced concrete girders. A reinforced concrete beam is connected between the reinforced concrete girders. The two ends of the reinforced concrete beam extend into the reinforced concrete girders. The frame type rail bearing beam structure is good in stability, larger in bearing force, convenient to construct and maintain, good in structural performance, remarkable in reinforcing effect and not likely to be damaged, components are connected tightly, and the maintenance frequency is reduced.
Description
Technical field
The present invention relates to a kind of support rail girder construction, particularly a kind of frame support rail girder construction.
Background technology
Middle low speed magnetic suspension track traffic belongs to a kind of novel traffic mode, current achievement in research both domestic and external is less, the circuit minority especially of operation is opened in the whole world, in March, 2005 Japan is only had to build middle low speed magnetic suspension railway comercial operation line-the East Hillside Line of opening and middle low speed magnetic suspension railway business operating line that in June, 2014, Korea S opened at present, and the middle low speed magnetic suspension traffic of China only has National University of Defense technology's test wire at present, Green City Mountain test wire, Tangshan experiment line, there is no the circuit formally put into effect, but also there is following problem: 1, because sleeper pedestal is arranged on buttress top, thus, the sectional dimension of buttress, sleeper pedestal can not be less than, the position of buttress must be determined according to sleeper position, require that construction control precision is high, especially at 3 in Curve Segment, the construction positioning difficulty of buttress is larger.2, for increasing the rigidity of buttress and the ability of resistance to deformation, propping up socle is often provided with vertical, straining beam, for saving engineering quantity, these are indulged, the sectional dimension of straining beam is less than the sectional dimension of buttress more, in construction, be difficult to make integral mold plate, buttress is with vertical, straining beam carries out monobloc cast, need first to construct buttress, construction is vertical again, straining beam, working procedure is many, 3, by the buttress type support rail beam of beam on elastic foundation design, top buttress is arranged on the armored concrete slab under it mostly, its integral rigidity is little, in lifting, in transportation, structure is yielding, prefabrication mode should not be adopted to construct, field cast-in-place is answered to construct.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the problems referred to above, provides one to have good stability, and carrying dynamics is larger, construction and safeguard also frame support rail girder construction eaily.
To achieve these goals, the technical solution used in the present invention is such: frame support rail girder construction of the present invention, comprise reinforced concrete floor, reinforced concrete floor is between two base plate backfill end face lines, reinforced concrete floor upper surface is provided with steel concrete longeron, steel concrete longeron is two, two steel concrete longerons are fixed on reinforced concrete floor, vertically reinforcing rib is provided with in steel concrete longeron, be fixed on reinforced concrete floor through steel concrete longeron bottom reinforcing rib, reinforcing rib top is fixed on steel concrete longeron inner top surface, reinforced concrete beams is connected with between two steel concrete longerons, reinforced concrete beams two ends extend in steel concrete longeron, reinforced concrete beams upper surface and steel concrete longeron top are in the same horizontal line, two steel concrete longeron two sides are all provided with water conservancy diversion rail bearing, water conservancy diversion rail bearing is connected with steel concrete longeron by adjusting bolt, also comprise a sleeper pedestal, be separately positioned on steel concrete longeron top and reinforced concrete beams upper surface bottom sleeper pedestal, sleeper pedestal top is provided with the section of track, the groove passed for sleeper pedestal is provided with in the section of track, be connected by pin between the section of track with sleeper pedestal.
Further, as a kind of concrete form of structure, more than one of reinforced concrete beams of the present invention.
Further, as a kind of concrete form of structure, one to two centimetre, interval setting between adjacent two reinforced concrete beams of the present invention.
Further, as a kind of concrete form of structure, reinforced concrete floor cross section of the present invention adopts rectangular configuration.
Further, as a kind of concrete form of structure, be welded on respectively bottom sleeper pedestal of the present invention on reinforcing bar in steel concrete longeron and reinforced concrete beams.
Further, as a kind of concrete form of structure, the section of track of the present invention is inverted trapezoidal structure.
Compared with prior art, the invention has the advantages that: this frame support rail girder construction has good stability, carrying dynamics is larger, construction and safeguard also more convenient, self have good structural, stiffening effect is obvious, not easily be damaged, connect closely between parts, reduce frequency of maintenance.
